So, Driving to work today there is a slight stumble, and an orange picture of a 4.7l V8 engine on my dash and the word CHECK below it.

I finished work and drove the 1.5 miles home slowly. Joined my wife for an adventure to Wall-Mart to buy a $79 ODBII tool. Already had a shop manual, Already had a spare COIL in tool bag.

I like when it takes longer to do a write up than the repair. :) The key to the simplicity of this was the ODBII scanner. Having the right tools can make all the difference in the world.

Thats cool. We had the same thing happen on my truck at Pismo. 5 min later, we were back in line at the poker run. Love the easy ones.

The scanner is a must have tool IMO. It was probably the first new tool I got after purchasing the 80. I now keep one in the wife's Subaru too. Nothing is worse than owning one but not having it with you.

Happy to see an easy fix.:thumb:
